If you are able to do 5 pull ups now and after 4 weeks you are able to do 9 pulls ups. Write an equation that represents the number of pull ups "y" you can do after "x" weeks.

The equation that that represents number of pull ups i can do after weeks is .

Step-by-step explanation:

Given:

Number of pull ups at the beginning  = 5

Number of pull ups after 4 weeks = 9

We need to write the equation for number of pull ups i can do after weeks.

Solution:

Now we will find the number of pull ups increased in 4 weeks.

number of pull ups increased in 4 weeks can be calculated by Number of pull ups after 4 weeks minus Number of pull ups at the beginning.

framing in equation form we get;

number of pull ups increased in 4 weeks =

So we can see that;

in 4 weeks = 4 pulls increase

in 1 week = Number of pull ups able to do in 1 week.

By using Unitary method we get;

Number of pull ups able to do in 1 week =

Now we can say that;

Let the number of pull ups you can do .

Let he number of weeks be .

So we can say that;

number of pull ups you can do after 'x' weeks is equal to Number of pull ups at the beginning plus Number of pull ups able to do in 1 week multiplied by number of weeks.

framing in equation form we get;

Hence The equation that that represents number of pull ups i can do after weeks is .
